Mouser: An open source alternative to Logi-Plus mouse software

Original Article ↗ Hacker News Discussion ↗

Overview of Mouser Project

  • Presented as an open-source replacement for Logitech Options+ on macOS, currently focused on MX Master 3S.
  • Welcomed as a way to avoid bloated, intrusive vendor software while still accessing advanced mouse features.
  • Some concern about longevity and maintenance; hope expressed for a community around it.
  • Limitations noted: currently only supports MX Master 3S, and unclear if it handles all hardware features (e.g., smooth scrolling is asked about explicitly).

Logitech Software Criticism

  • Widespread consensus that Logitech software (Options+, G Hub) is:
    • Bloated (hundreds of MB RAM, sometimes >1 GB).
    • Buggy (broken updates, high CPU usage, random input issues).
    • Pushy with “AI” features, ads, telemetry, and background services.
    • Annoying to install/manage, sometimes requiring special permissions and multiple apps for different devices.
  • Offline / “air-gapped” Logitech installers are seen as less bad, but many plan to avoid future Logitech purchases due to software quality.

Logitech Hardware: Mixed Opinions

  • Some praise Logitech mice (especially MX line and G-series) for ergonomics, surface compatibility, and scroll-wheel behavior.
  • Others report:
    • Short lifespans (scroll-wheel failures, worn switches, degraded rubber coatings).
    • Perception that competing brands (Razer, HyperX, SteelSeries, Corsair, etc.) now offer better build quality.
  • Experiences differ; some never see degradation, others repeatedly hit failures or sticky coatings.

Alternative Tools (macOS)

  • Popular macOS alternatives mentioned:
    • SteerMouse (longstanding, seen as reliable and powerful).
    • MacMouseFix, BetterMouse, LinearMouse, BetterTouchTool.
  • These tools provide button remapping, smooth scrolling, per-app settings, and in some cases full Logitech device support.

Alternative Tools (Linux & Cross-Platform)

  • On Linux, Piper + libratbag, Solaar, and logiops are highlighted for configuration and receiver management.
  • Some report good “set it and forget it” experiences; others struggle with device support or limited remapping.
  • For keyboards, kanata is suggested as a powerful software remapper independent of vendor tools.

Other Discussion Points

  • Frustration that simple mouse/keyboard configuration now requires heavy frameworks and web-like stacks.
  • Desire for FOSS, lightweight, per-device/per-app configuration tools and better on-device memory so background daemons are unnecessary.
  • Some humor and concern about the “Mouser” name clashing with the electronics distributor’s brand, but legal implications are debated as scope-dependent.
